Hi. Could someone please explain the differences between half and full-bridge (reverse and non-reverse) PWM? The single is easy. If possible, please include sample waveforms. Thank you.
 

hi,
The PWM frequency and duty cycle are the same for forward or reverse, when using a full H Bridge BUT dont have both Fwd and Rev PWMs active at the same time.

A posting of a sample waveform would be meaningless, it could be a range of square wave frequencies, with a Mark/Space period of 0%Thru 100%
